Cloud RAN relies on virtualization technologies to decouple network functions from the underlying hardware infrastructure, enabling greater flexibility, scalability, and cost-efficiency. The correct answer identifies virtualization as a fundamental component that allows multiple network functions to run on shared physical resources. This approach is essential for implementing Cloud RAN, as it transforms traditional RAN architectures into a more dynamic and adaptable environment where resources can be allocated as needed.

While other concepts like Network Function Virtualization (NFV) and Software-Defined Networking (SDN) are integral to the overall architecture of virtualized networks, they are specific implementations or methodologies within the broader scope of virtualization. NFV refers specifically to the virtualization of network services that historically run on proprietary hardware, while SDN emphasizes programmability and centralized control over network resources. Multi-access Edge Computing (MEC) focuses on bringing computational power closer to the user at the edge of the network but does not directly describe the virtualization aspect of RAN.

In summary, the emphasis on virtualization captures the essential principle that enables Cloud RAN's flexibility and capability to efficiently manage network services by utilizing virtualized resources.
